What organs are there on the head of cephalopods?

Cephalopods, a class of molluscs that have bilateral body symmetry, are also characterized by more complex behavior and structure than other molluscs. A distinctive feature is the presence of legs on the head of mollusks, hence the name of this class.

Cephalopods mainly live in seas and oceans with a high salt content, they are free-swimming molluscs, but some representatives live on the bottom.

Modern cephalopods include cuttlefish, squid, octopus.
The body of the molluscs is divided into a large head and trunk. On the head is a mouth, which is surrounded by tentacles, and large eyes. Most species have suckers on the tentacles.
